Gastric Intubation

The objective of our experiments was to study the persistence and dissemination of orally administered Salmonella in smoltified Atlantic salmon. In experiment 1, salmon kept at 15°C were fed for 1 week with feed contaminated with 96 most-probable-number units of Salmonella Agona per 100 g of feed and then starved for 2 weeks. Samples were taken from the gastrointestinal tract and examined for Salmonella 1, 2, 8, 9, 15, and 16 days after the feeding ended. In experiment 2, Salmonella Agona and Montevideo were separately mixed with feed and administered by gastric intubation. Each fish received 1.0 × 108, 1.0 × 106, or 1.0 × 104 CFU. The different groups were kept in parallel at 5 and 15°C and observed for 4 weeks. Every week, three fish in each group were sacrificed, and samples were taken from the skin, the pooled internal organs, the muscle, and the gastrointestinal tract and examined for the presence of Salmonella. The results from the two experiments showed that the persistence of Salmonella in the fish was highly dependent on the dose administered. Salmonella was not recovered from any of the fish that were fed for 1 week with the lowest concentration of Salmonella. In the fish given the highest dose of Salmonella, bacteria persisted for at least 4 weeks in the gastrointestinal tract as well as, to some extent, the internal organs. The present study shows that under practical conditions in Norway, the risk of Salmonella in fish feed being passed on to the consumer of the fish is negligible.

Protein Free Diet

An histidine-devoid but otherwise balanced amino acid mixture depressed food intake from 2 hr after its gastric intubation. It induced conditioned aversion to an odour incorporated in a protein-free diet presented for 6 h following intubation. In other rats, a balanced amino acid mixture established conditioned preference for odour presented in the same diet for 6 h following intubation. The degree of preference was considerably less than the degree of aversion.

Group I control rats, Group II rats mammary carcinoma induced with DMBA (25 mg in 1 ml olive oil) by gastric intubation. Group III, IV and V DMBA induced rats were treated with TD (400 mg/kg. b. wt/day), PGG (30 mg/kg. b. wt/day) and standard drug, Cyclophosphamide (30 mg/kg. b. wt/day), respectively for 48 d by gastric intubation. Group VI and VII rats served as TD and PGG treated controls, respectively for 48 d by gastric intubation. At the end of the experimental period, the rats were anaesthetized and sacrificed. Mammary glands were isolated and used for biochemical assays and histopathological evaluation.</p><p><strong>Results: </strong>In rats with cancer, the lipid peroxide levels (LPO) were significantly increased and mitochondrial antioxidant levels were decreased. Treatment with TD and PGG decreased LPO levels and increased mitochondrial antioxidant status in mammary carcinoma bearing rats. Histopathological analysis also confirmed the therapeutic effect of TD and PGG. No significant adverse effect was observed in sole drug treated group of rats.</p><p><strong>Conclusion: </strong>TD and PGG have definite therapeutic effect in experimental mammary carcinoma and inhibit growth of cancer cells by restoring mitochondrial antioxidant status and energy metabolism to normal states.</p>

Introduction: Nicotine, a major component of cigarette smoke, alters ovarian function and Ajwa (Phoenix dactylifera) being an antioxidant prevents its toxicity. Aims & Objectives: This experimental study was designed to evaluate protective effect of Ajwa against ovarian toxicity induced by nicotine in adult albino rats. Place and duration of study: The study was conducted in the Department of Anatomy, Federal Postgraduate Medical Institute, Shaikh Zayed Medical Complex, Lahore for duration of 3 months (January 2017-March 2017). Material & Methods: 40 adult female albino rats were divided into four equal groups. 1ml distilled water was given to the rats of control (A) group by gastric intubation, experimental group B was given nicotine injection intraperitoneally (0.1 mg/kg body weight) for 28 days. The rats of experimental group C were given Ajwa fruit extract 1gm/kg body weight daily by gastric intubation, while rats of experimental group D were given 0.1mg/kg body weight nicotine intraperitoneally plus 1gm/kg body weight Ajwa fruit extract by gastric intubation for 28 days. Results: In group B, secondary and Graafian follicles were mostly atrophic, degeneration of granulosa cells, pyknotic nuclei and stromal vacuolization were present. Zona pellucida was torn and irregular. Mean diameters of secondary and Graafian follicles were significantly lower in nicotine group B (p-value<0-001*). Experimental group C revealed normal histological architecture and diameter of ovarian follicles. Near normal restoration of follicular structure was seen in group D. Conclusion: Ajwa fruit extract is counterbalancing for nicotine induced oxidative stress in ovarian follicles of rat, so it may be useful to improve infertility or sub-fertility induced by smoking in females.

The hypothesis addressed was that metabolic activity within specific brain areas may be altered to depict peripheral metabolic status. Sixty-three female Sprague-Dawley rats (225 g) received 150, 100, or 50% of normal intake by gastric intubation for 7 days. The incentive for spontaneous feeding would be inhibited in 150% fed rats (anoretic), stimulated in 50% fed rats (hungry), and maintained in 100% fed rats (control). Glucose flux through the gamma-aminobutyric acid shunt of the ventrolateral hypothalamus was 32% lower in hungry rats and 35% higher in anoretic rats relative to control values. Glucose flux through the pentose shunt of the ventromedial hypothalamus was 111% lower in hungry rats and 152% higher in anoretic rats relative to control values. Pentose shunt activity in the area postrema nucleus of the solitary tract (AP NTS) was 116% lower in hungry rats and 60% higher in anoretic rats relative to control values; however, hungry and anoretic rats had AP NTS pentose shunt activities that were not different from control values but were different from each other. The data demonstrate that within selective brain sites, specific pathways for glucose oxidation are affected by energy intake and may be used by the rat to assess and respond to changes in peripheral energy status.

Mn Concentrations

1. Very little is known about the biological availability of manganese from human milk and other infant milk diets. To determine the relative Mn availability, and to examine whether the age and the duration of previous fasting affect Mn absorption, sucking rats were given human milk, bovine milk and infant formula (regular Similac; Ross Laboratories, Columbus, OH) extrinsically labelled with 54Mn.2. Milk diets were given by gastric intubation and the radioactivity of the carcass, liver and digestive tract was measured 3 h after feeding.3. The concentration of endogenous Mn was lowest in human milk (7–10 μg/l) and highest in rat milk (140–165 μg/l). Increasing the non-radioactive total Mn concentrations of either human milk or bovine milk up to 150 μg/l did not affect the absorption of 54Mn by 10-d-old rats.4. No significant (P> 0.05) difference in 54Mn absorption was found among the three milk diets (human milk, bovine milk, infant formula) in 8- to 11-d-old rats. However, significantly more (P< 0.05) 54Mn was absorbed from human milk and infant formula than from bovine milk when 13-d-old rats were used.5. 54Mn radioactivity detected in carcasses of 8-, 9-, 10- and 11-d-old rats ranged from 25 to 27% of the dose from various milk diets. The activities of 54Mn in the carcasses of 13-d-old rats were 15, 11, and 16% of the dose from human milk, bovine milk and infant formula respectively.6. The trend of 54Mn incorporation into liver was similar to that of the carcass and over 60% of the absorbed 54Mn was incorporated into the liver regardless of the type of milk used.7. Absorption of 54Mn from extrinsically labelled rat milk using 9- or 10-d-old sucking rats was similar to its absorption from infant formula.8. The absorption of 54Mn from the three milk diets decreased with age of the neonatal rats and 54Mn absorption from human milk, bovine milk, infant formula as well as rat milk was affected similarly by duration of previous fasting.
